SPECIFICATION forming part bf Letters Patent No. vse is aetea March 29,1904.. Application filed May 5 ,1902. Serial No. 105,888. (No modell) Toall whom it may-co nc erm V v Be it known that I, GUsTAvHILLnR, asubject of the King of Saxony, residing at Zittau, in the Kingdom ofSaxony and Empireof Germany, have invented new and useful Imfollowing isa specification.

whereinthe individual amounts paid are indicated by. indicatorwvheelsthe numbers, of which-may .be seen through holes arranged in the casingof the apparatus and which are directly operated-by keys or groups ofkeys, said indicating-wheels returning to, zero before manipulation, soas to be ready to register the transaction. Of course a separateindicator-wheel is provided for each valuesuch as for cents, tens ofcents, for dollars, and tens of dollars, &c.and hitherto a separate keyindependent of the others was required for each indicator-wheel. Thisfact has made the control and manipulation of this class of machines sodifficult that registers with indicator tablets or cards were preferredto apparatus of the class here shown.

The purpose of this invention is to reduce the number of keys and tothus simplify the whole mechanism of such machines. This keys, one setfor the units and one for the tens of each denomination ofthe severalcoins, (cents, dollars, &c.,) each set consisting, of course, of tenkeys numbered from 1 to 0, and these keys are so arranged as to be usedfor the units or tens of any denomination, as may be required.

In the accompanyingdrawingsI have shown a preferred constructional formof the cashindicator.

Figure 1 is a longitudinal section; Fig. 2, a section on the line A B,and Fig. 3 a section on the line C D, of. Fig. 1. Fig. 1 is a section onthe line N O, and Fig. 5 a section on the line Y Z, of Fig. 1. Fig. 6 isa detail view in cross-section on the line J K ofFig. 1, showing one ofthe ratchet-wheels and pa-wls; and Fig. 7 is a similar view of thecam ttaken in section of the cam-shaft on line L M of Fig. 1, thecrank-handle being shown in dotted lines.

The longitudinal section, Fig. 1,'is taken dition of numerals. Forinstance, one of the numberswheels is marked S, the next similar wheelSi, and so on- This 1nvent1on. relates to a cash-ind cator Theindicator-wheels S S Siand S" are adapted to turn 1 1. 011 the commonshaft'VV but unable to move axially thereon. .S' and S are theindicator-wheels for the tens and units of dollars, S and S those forthe tensand units of cents. For each indicator-wheel there is provided atoothed coupling, one half, a, of which is secured to the indicatorwheelitself, while the other half, 6, is firmly connected with thecommunicating wheel P and capable of turning loosely upon the shaft WThe communicating wheels P 1, 2, 3, 4 engage with toothed sectors Q, 1,2, 3, 4, which can turn loosely upon a common shaft 0, but are immovablein the axial directionand which are subjected to the action of springs0, 1, 2, 3, 4:, tending to turnthe same backto their position of restand attached to arms d, firmly united with such sectors.

Y, Y YYY, Y and Y are stops secured firmly in position, which, whilepermitting purpose is attained by using only two sets of rotation of thewheels S, &c., prevent the same from moving axially, and o, c c and 0are each a stop adapted to stop the adjacent number-wheel at 0 upon thereturn movement thereof, ready for the next. transaction. These arms areconnected by rods 6 with two lifting-rods f g, each of which is actedupon by agroup of keys,.the endsof the keys T taking below the rods gand f. Accordingly the lifting-rod f is. moved only by the group oftens-keys and the lifting-rod g only by the group of units-keys. Inconformity therewith the toothed sectors Q and Q of l theindicator-wheels S and S for the tens of dollars and tens of cents areconnectedby rods 6' and c with the lifting-rod f of the group oftens-keysand the toothed sectors Q? and Q} of the. indicator-wheels forthe units of dollars lifting-rod g of the group of units-keys.

According as the cents indicator-wheels or the dollars indicator-wheelsare coupled with v and units of cents by rods 0 and 0 with the thegroups of keys, which maybe effected by a simple changing device, thegroups of keys will act upon the indicator-wheels for the tens and unitsof dollars or upon the indicatorwheels for the tens and units of cents.A suitable arrangement is shown in the drawings. The couplings of thecents indicator-wheels are arranged, together with those of the dollarsindicator-wheels, upon the shaft W in such a manner that some are throwninto gear on the disengagement of the others, all the couplings beingout of gear in a middle position.

To obviate the use of a special disengagingrod or the like for thecouplings, the shaft W in the constructional form shown is adapted to bedisplaced axially, and the couplings Z) engage by pins it with annulargrooves in the shaft 1V so that they are compelled to take part in thedisplacement of this shaft. The shaft 1V is usual'ly forced by a spring2' or by a weight toits extreme position on the left'of Fig. 1, in whichthe coupling a 6 of the indicator-wheels S S are in gear for theregistration of cents.

The shaft W is placed in its extreme position on the right by a pressureupon the same in the direction of its axis contrary to the action of thespring 1', the couplings of the indicator-wheels S S being thrown out ofgear, but those of the indicator-wheels S S being thrown into gear, sothat these indicatorwheels are now connected with the two groups ofkeys.

In the constructional form represented the displacement of the shaft Win opposition to the action of-the spring itakes place by a specialchange-key L, Figs. 1, 2, 3, and 4, connected by means of a rodl and abell-crankm n, which is fitted to turn about a fixed pivot 0 with atwo-armed lever p q. This lever can turn about a fixed pivot '7" and byone arm, 12, takes hold of the arm n of the bell-crank lever m a; but bythe other arm, (1, it takes hold of the shaft WV. Therefore ondepressing the key is the displacement of the shaft Vt takes place inopposition to the spring a. This displacement is limited by a stops onthe side M of the frame containing the mechanism.

For enabling the indicator-wheels to be returned to zero after theregistration of the whole amount it is necessary to disengage the pawlsK which, engaging with the ratchetwheels R 1, 2, 3, 4, fix them in theposition they have reached, and to impart to the indi cator-wheelsthemselves a return movement corresponding to the partial turningmovement necessary for changing their position. At the same time all theindicator-wheels have to be completely uncoupled from the groups ofkeys. This is accomplished in the constructional form shown by changingthe shaft W to its middle position, wherein all the couplings a Z) arethrown out of gear. For this purpose I have provided on the side M ofthe frame containing the mechanism of the cash indicator a fixedcam-disk t, the cam of which engages with a corresponding notch in thefront of a counter-disk 6, arranged upon the shaft 1V By turning theshaft W T2 through the medium of the crank 168 in the contrary directionto that of the turning movement of the indicater-wheels when changingthem in position the cam of the disk 6 leaves the notch in the disk 25"and slides upon the front of the latter. By the axial displacement ofthe shaft W 2 thus effected this shaft is placed in the middle position.(Represented in Fig. 1.) At the same time a tappet n, furnished in abroad annular groove of the shaft for each of the indicator-wheels S 1,2, 3, 4:, takes behind a corresponding projection 10 in the bore of theindicator-wheel, so that the indicator-wheels will be carried away inthe return turning movement of the shaft. The disengagement of the pawlsK is effected by a cam-disk t, connected with the disk 6 and acting uponan arm 6 on the shaft t, common to the pawls K,

so that the arm will be lifted and the pawl K disengaged, Fig. 3. By oneturn of thecrank a and thus also of the shaft WV the indicatorwheels S1, 2, 3, 4 are turned back to zero and the spring 2' effects thedisplacement of the shaft W back to its extreme position on the left ofFig. 2 and the engagement of the couplings of the wheels S S.

In the extreme positions of the shaft W T2 the projections w in theinterior of the bore of the indicator-wheels can pass the tappets e onthe shaft W without touching them.

WVhat I claim as my invention, and desire to secure by Letters Patent,is-
